Wave reflected from a wall:interference between original wave and reflected wave

[Fu-Kwun Hwang]

The following simulated a circular wave propagate.
When wave bounce with a wall, a reflected wave is generated.
You can find out interference pattern between the original wave and the reflected wave.

You can use sliders to change wavelength(r) or speed(v) of the wave.
The location of the wave source can be changed with mouse drag (in the x-direction only).
